The following post from Erin Hodgess gives an example of how to do it:

Please try this:

z1 <- rexp(100)
z2 <- rexp(100)
z3 <- rexp(100)
z4 <- rexp(100)
par(mfrow=c(2,2),oma = c(0, 0, 3, 0))
curve(dexp,from=0,to=5)
hist(z1,main="first")
hist(z2,main="second")
hist(z3,main="third")
mtext("Densities", outer = TRUE, cex = 1.5)

Hope this helps.

Sincerely,
Erin
